The true statement is that they require ultraviolet light to react.

The reaction between methane and chloride is a free radical substitution.

Chlorine molecule (Cl2)  reacts with light to produce 2 radicals Cl ·, which will start a chain reaction, because the Cl · radicals react with CH4, to produce CH3· radicals and one CH3· radical joind to a Cl· radical to produce CH3Cl.

This can also lead to a double or triple substitution obtaning CH2 Cl2 or CH Cl3.  Or even more substitution to obtain C Cl4.

They require ultraviolet light to react.
